IMPROVEMENT IN LAMP STEAM GENERATORS AND BOILERS.

Specification forming part of Letters Patent No. 177,930, dat

ed May @0, 1876; application filed March 11, 1876.

is employed for generatingheat for the purpose of heating water forvarious uses; and consists of a cylinder surrounded by a vessel forholding water, said cylinder being placed over a lamp-burner, so as toserve as a chimney thereto, and to be" heated by the flame thereof, andthus heat the contents of the vessel surrounding the cylinder. Thevessel is covered with a cap having a hole in the center, through whichthe cylinder protrudes, and to this cap is secured, by pipes projectingthrough the same into the heating-vessel, a

steam-dome having a conical bottom.

To enable others to fully understand my invention, I proceed to describethe same in detail with the aid of the accompanying drawin g, in which-Figure 1 is a side elevation of my appara- "tus; Figs. 2 and 3, side andsectional views,

respectively, of the apparatus, with a cap attached instead of asteam-dome.

A, Fig. 3, is a cone-shaped cylinder, surrounded by a vessel, B,designed to contain water. The said cylinder A and vessel B are to besupported upon suitable legs a a, between which is placed a lamp, 0,bringing the flame underneath the cylinder A, which forms the chimneyfor the lamp. The vessel B is. pro vided with a loose cover .or cap, D,havinga hole in the center, leaving the top of the cylinder A open.

For the purpose of generating steam I propose to make the vessel B on alarger scale, as may be required, and have two or more cylinders throughit for employing more lamps, and'surmount the same with a steam-dome, F,(seen in Fig. 1,) connecting it with the vessel by pipes G G. Said domeI make with an inverted cone for its bottom, and place the apex directlyover the center of the chimney A. In this manner it receives the heatfrom the chimney without retarding the draft. To the top of the dome isplaced a neck and cover for filling, and from the top of the dome alsopipes may be attached for conveying away the steam. This is designed fora cheap portable apparatus for generating steam for heating or warmingrooms, the apparatus being connected with suitable heat-radiators.

I have shown in Figs. 2 and 3 a cup, E, for heating water, &c., attachedto the cover D, merely to' illustrate the principle of operation, andnot intended to be claimed as entirely original with me. Fig. 3 shows,in section, the details of construction of the cylinder andwater-vessel.

Having described my invention, I claim- The cylinder A, surroundingvessel B, having legs a a, and heating device O, in combination with thesteam-dome F, having a conical bottom, pipes G G, and movable cover D,all constructed substantially as shown.
